Convert Class Components to Functional with Hooks, Migrate Tests to Jest, and Transition to TypeScript

[PatrickPD]

This pull request introduces several modernizations and improvements to the react-extension-point package, aimed at enhancing its maintainability and aligning it with current best practices in the React ecosystem.

Key Changes:

1. Conversion of Class Components to Functional Components:

   • All class components have been refactored into functional components.
   • Associated logic has been updated to use React Hooks, ensuring a more concise and readable codebase while preserving the original functionality.

2. Migration of Tests from TAP to Jest:

   • Tests have been transitioned from the TAP framework to Jest.
   • Care has been taken to maintain the tests as close to their original format as possible, ensuring continuity in testing methodologies.
   • This migration leverages Jest's robust features and community support, enhancing the testing experience and future-proofing the test suite.

3. Conversion of Codebase to TypeScript:

   • The entire codebase has been converted to TypeScript.
   • This shift not only improves type safety and developer experience but also aligns the project with the growing trend of TypeScript adoption in the React community.

Testing and Quality Assurance:

• All existing tests have been carefully adapted to work with the new code structure and Jest framework.
• I have ensured that all tests pass successfully, maintaining the reliability and integrity of the existing test suite.

This refactor is a significant step towards modernizing the react-extension-point package, offering improved code readability, enhanced developer experience, and better maintainability. I believe these changes align well with the project's ongoing development and future growth.

Looking forward to feedback and suggestions from the maintainers and contributors of react-extension-point.

Best regards,
